This invention relates to ironing machines and has to do with means for connecting utility devices to the motor of the ironing machine to be driven thereby.

My invention is intended particularly for use with an ironing machine having a box-like cover which, when in closed position, encloses the roll and shoe of the machine, the top of the cover providing a table top, such as is disclosed in the patent to Carl F. Anderson and Rudolph W. Janda, No. 1,656,656, issued January 17, 1928. One of the main objects of my invention is to provide a machine of this character having a power take-off, accessible when the cover is closed 1 in its entirety so as to provide a continuous and unobstructed table top, and a take-off unit connectible to the. power take-off for driving utility devices from the motor of the ironing machine. A further object is to provide a power take-off unit positionable, when in inoperative position,

closely adjacent the machine so as to avoid objectionable projections, this unit when in use being disposed so as to support utility devices in proximity to the table top so that articles disposed thereon are conveniently accessible with relation to the utility devices. A further object is to provide a power take-01f unit, which when in operative position is spaced an appreciabledistance from the machine and provides a support for utility devices associated therewith. Further objects and advantages of my invention will ap pear from the detailed description.

The ironingmachine is, in general, similar in construction and operation to the machine disclosed in the above identified patent of Carl F. Anderson and Rudolph W. J anda. This machine comprises the bed 1 supported bya suitable frame including legs 2, a box-like cover 3 hinged to the bed plate 1 at the rear portion thereof, this cover, when closed, resting upon the bed plate and enclosing the ironing roll 4 and shoe 5 which cooperates with the roll, the top of the cover providing a table top. A gear housing 6 depends from bed plate 1 at one end thereof and contains a worm gear 7 with which meshes a worm 8 suitably secured on a drive shaft 9 extending into the gear housing. This shaft is connected by a flexible coupling 10 to the shaft of an electric motor 11 suitably suspended from bed plate 1. The worm gear 7 drives suitable mechanisms for rotating the roll .4 and moving the shoe 5 toward and away from the roll, as required, suitable means being provided for controlling operation of the shoe and the motor.

Gear housing 6 isprovided, at the outer end thereof, with a socket 12 into which the outer end portion of .shaft 9 extends, this socket being concentric with theshaft. A collar 13 is pinned or otherwise secured on shaft 9 and contacts the wall of the housing at the inner end of socket 12. The end of shaft 9, which projects outwardly beyond collar 13, is cut to produce. oppositely directed clutch teeth 14.

Two lugs 15 depend from housing 6 and receive a rod 16 loosely mounted in the lugs for sliding and rotary movement. This rod is parallel with shaft 9 and is secured in endwise adjustment by a spring latch 1'7 mounted upon the inner lug 15.

screwed or otherwise suitably secured in lug 15, a

, plunger 19 slidable in the casing 18, and an expansion coil spring 20 mounted about the plunger and confined between the nose 21 thereof, which is of increased diameter, a'nda shoulder22 or flange at the outer end of casing 18. A thimble 23 is suitably secured in a knob 24 and the outer end of the plunger 19 is screwed into this thimble. The nose of the plunger is adapted to engage into either one of two bores 25 in the-rod 16 and extending radially thereof, these bores being spaced apart lengthwise of the rod and also being spaced apart circumferentially of the rod. A suitable stop member, such as a cotter pin 26, is provided at the inner end of rod 16 to prevent complete withdrawal thereof from the lugs 15. The latch 17 provides means for releasably securing rod 16 in lengthwise adjustment as wellas in adjustment aboutitsaxis. v

The outer. portion of rod 16 extends through two spaced lugs 28 depending from lower'section 29 of a gear casing 30 of approximately rectangular shape in plan, upper section 31 of this casing being secured'to lower section 29 in a suitable manner, as by means of screws 32. Casing 30 is secured on rod 16 in a suitable manner, as by means of pins 33 passing through lugs 28 and rod 16. The gear casing 30 is thus attached to rod 16 for adjustment toward and away from the end of the ironing machine by sliding the rod through lugs 15.

A sleeve 34 is secured at its outer end, by means of screws 35, to the inner side of section 29 of casing 30 at the ends thereof remote from rod 16. The inner end portion 34a of this sleeve cohforms in size andshape to socket 12 and is adapted to fit snugly therein. 'A shaft 36 is rotatably mounted through sleeve 34 and a clutch'head 37, disposed within end portion 34a"of the sleeve, is secured by a pin 38 upon the adjacent end of shaft 36. A worm 39 is secured upon the other end of shaft 36, within casing section 29, suitable anti-friction and thrust bearings 40 being which projects upwardly from the bottom wall of the casing. Gear 49 meshes with a pinion 50, pinned or otherwise suitably secured upon a stub shaft 51 rotatably mounted, at its lower end, in a boss 52 on the bottom wall of the casing. Stub shaft 51 extends through a bearing collar 53 depending from a stufling box casing 54 formed integrally with top wall 55 of upper section 3l of casing 30. A stufllng box structure 56 of suitable type is disposed within the casing 54 and provides a grease tight closure about the stub shaft 51, which projects above top wall 55 of the gear casing for an appreciable distance. The upper end of stub shaft 51 is cut away at its opposite sides to provide a key element 57 adapted to engage into a corresponding slot of a member to be driven by the stub shaft. A boss 58 depends from top wall 55 and is disposed to prevent ob-'- jectionable upward movement of connecting rod 45 relative to the pins 44 and 46. A Suitable.

gasket 59 is disposed between the sections 29 and 31 of casing 30 to prevent leakage of grease or lubricant therebetween.

Clutch head 37 is provided with a bore 60 for reception of the outer'end portion of shaft 9, within which bore are disposed two elements 61 which coact, with teeth 14 of shaft 9 for coupling the latter to head 37. When the inner end 34a of sleeve 34 is disposed within socket 12, the gear casing 30 is spaced away from the end of bed plate 1, as in Figure 1, and shaft 36 is coupled to shaft 9 through the coupling head 37 and elements61 and teeth 14. With the casing in this position, the'nose 21 of detent 19 engages into bore 25 adjacent the inner end of rod 16, thus holding the gear casing 30 against movement away from the ironing machine. It will also be noted that the end 34a of sleeve 34 coacts with the surrounding wall of socket 12 to hold the casing 30 against turning movement on the axis of rod 16, this rod and the sleeve cooperating to hold the gear casing in horizontal position.

' Upper section 31 of casing 30 is provided with a boss 65 extending from the inner side thereof, this boss and sleeve 34 being disposed equidistant from and concentric with rod 16. Boss 65 conforms in sizeand shape to socket 12 so as to fit snugly therein when casing 30 is in its inner or inoperative position, at which time the detent engages into the outer bore 25 of rod 16, boss 65 1 cooperating with the surrounding wall of the socket 12 to hold casing 30' against turning movement on the axis of rod 16. Referring more particularly to Fig. 3, it will be noted that the casing 30 is disposed at a considerable inclina- 1 tion downwardly and rearwardly of the ironing machine, when in inoperative position, so that the upper end of stub shaft 51 is disposed well below the upper surface of bed plate 1. This is advantageous as avoiding objectionable projections above the bed plate.

The form of my invention so far described is intended for use with a clothes washer including a cylindrical tub 66, provided with a suitable cover 67.- A multi-armed agitator 68 is disposed 1 within the tub and comprises a central hub 69 and a circular base plate 70. This base plate is secured to the bottom of the tub by screws. 71 passing through the tub bottom and screwing into base plate 70, rubber bumpers 72 being provided on the lower ends of these screws. A suitable packing disc or gasket 73 is disposed bo tween p1ate'70 andbottom wall 74 of the tub to provide a water-tight closure therebetween. A flanged-thimble 75 extends through the tub bottom and screws into the lower end ofhub 69.

A coupling member 76 ispinned or otherwise suitably secured in the upper portion of hub 69 and is provided with a diametrical-slot 77 adapted for reception of the tongue or key 57 at the upper end of stub shaft 51. Hub 69 seats upon the' stub shaft which thus supports the washer, including the tub 66, it being noted that the bumpers 72 are disposed to clear casing 30, and that bushing 79 seats upon, the upper face of the gear casing "to provide a supplemental support for the washer. When shaft 36 is coupled to shaft 9 to be driven thereby, stub shaft 51 is oscillated by means of worm 39 and the gears 41 and 47 and associated parts, thus oscillating the tub 66 so that the articles contained therein are thoroughly agitated by means of the agitator 68 for washing the same in the same manner, in general, as in washing machines of 1 the do y type- The modified form of power take-off unit illustrated in Figs. 6 and 7 is quite similar to that shown in Figs. 4 and 5. A stud 80 is disposed in the lower end portion of a sleeve 81 which replaces stub shaft 51 of Figs. 4 and 5. Pinion 50 is suitably secured to this stud and the sleeve 81, as by being pinned thereto. The upper portion of stud 80 is cut away to provide a semi-cylindrical clutch element 82 adapted for cooperation with a similar element at the lower end of a shank inserted into sleeve 81 from the upper end thereof, this shank being suitably secured to a utility device, such as a washer, to

be oscillated in the same manner as the washer illustrated in Fig. 8.

A worm gear 83 is rotatably mounted on a bearing boss 84 within the gear casing and adjacent the outer end of shaft 36. This gear is suitably secured to a centering stud 85, which extends into the boss 84, and is provided with an upwardly extending collar 86 from the upper end of which extends a reduced neck 8'7. Neck 87 of the gear is rotatably mounted through a bearing collar 88 depending from a stuffing box casing 39 formed integrally with and depending from the top wall of the gear casing. A stuffing box structure 90 of suitable type is disposed within the stufling box casing 89 and provides a grease or lubricant-tight closure about collar 8'7. A stud 91 is pinned or otherwise suitably secured in collar 87, the upper end of this stud being cut to provide two oppositely disposed clutch teeth 91a. A retaining ring 92 is secured, by screws 93, to the upper face of top wall 55 of the casing concentrically with collar 87, it being noted that this ring is disposed an appreciable distance above the stufiing box structure 90 to provide a space 94 in the nature of a socket for reception of an attaching element of a utility device. The ring 92 is provided, at diametrically opposite sides thereof, with web elements 95 the inner edges of which constitute chords of the ring and form, with the intercepted arcs thereof, an opening 96 having fiat sides and rounded ends. This opening is adapted for reception of an attaching member 97 of a utility device, such device including a standard 98 to which member 97 is connected by a reduced neck 99. Member 97 is spaced from the under face of standard 98 a distance corone of the web elements 95 of ring 92 to limit turning of standard 98 beyond the position in which the ends of member 9'7 engage beneath webs 95. In this manner the utility device is positively attached to the casing of the takeoff unit and shaft 101is simultaneously coupled to stud 91 to be driven thereby.

In Fig. 9 I have illustrated a utility device in the form of a beater or mixer 105 which comprises an upper member 106 hinged at 107 to standard 98. This mixer includes a head 108 fromwhich depend shafts, one of which is shown at 109, provided at their lower ends with suitable beating or mixing members 110. The mixer 105 is so disposed that the members 110 extend into a mixing bowl 111 supported by a shallow tray 112 to which is secured a shank 113 which extends into bore.114 extending from the upper end of boss 58, the lower end of shank 113 being rounded at 113a. In this manner the mixing bowl 111 is supported forrotation on a vertical axis and, during the rotation of the mixing members 110 the contents of the bowl are thoroughly beaten or mixed and the bowl is slowly rotated, thus assuring thorough mixing or beating of the materials within the bowl.

In Fig. 10 I have illustrated a fruit juice extractor attached to the take-off unit and comprising a standard 98 supporting a suitable bowl 115 responding to the thickness of ring 92. A bush-.

ing 100 is secured in standard 98 and extends through neck 99. vA shaft 101, for driving the utility device, is rotatably mounted through bushing 100 and has its lower end cut to provide oppositely disposed clutch teeth 102 which cooperate with clutch teeth 91a for clutching shaft 101 to stud 91. A worm 103 is secured on the outer end of shaft 36 and meshes with worm gear 83. The pitch of worm 103 is such that the gear 83 is driven at high speed relative to the speed of rotation of gear 41. In this manner, shaft 101 of the utility device is driven at high speed from shaft 36 of the power take-off unit. In applying the utility device to the take-ofi unit,

member 97 is inserted through opening 96 of ring having an'outlet 116 for discharging the juice into a glass or like receptacle 117 seating in a depression 118 in top plate 55 of casing 30. A reaming head 119 is suitably mounted within bowl 115 and has driving connection with shaft 101 to be driven thereby when halves of lemons, oranges, or other-fruits are pressed down upon the. head 119.

It will be noted that in both forms of my invention disclosed, the various utility devices are supported by the power take-01f unit in such position that the table top of cover 3 affords convenient and readily accessible means for sup porting articles to be treated or operated upon by the utility devices, or articles which have been removed from such devices.

As above indicated, and as will be understood by those skilled in the art, changes in construction and arrangement of parts of my invention may be resorted to without departing from the field and scope of the same, and I intend to include all such variations, as fall within the scope of the appended claims, in this application in which the preferred forms only of my invention have been disclosed.
